Verified Patient Reviews
Good, but very annoying that I had to fill out paperwork with all the same information that I already painstakingly filled out on Zocdoc.
The front desk girl who checked me out had a bit of an attitude but other than that the doctor was excellent and I was seen in a timely manner.
he's great. his front office not so much but i think they were just overwhelmed.
Went to see Dr. Nassos about wrist pain. He was very warm and professional. After going to primary care physicians and getting zero information.. Dr. Nassos knew right away my diagnosis. What a relief!
The doctor seemed very nice and knowledgeable. He listened to everything I said and asked a lot of questions to learn more about my symptoms. The wait to be seen despite having checked in early was really long, though.
Dr. Nassos was awesome! He was very friendly, knowledgeable, and didn't make me feel rushed or anything. He answered all my questions and was very patient. The staff was very friendly as well. They got me in and out of there quicker than I expected. I will definitely be coming back and will be referring him to everyone I know who needs an orthopedic.
Nice conservative approach!
He seemed very knowledgable and professional. There was almost no wait time and everyone in the office was friendly!
He was very good and thorough. Nice people and nice facility.
Dr. Nassos was very pleasant and responsive to my concerns. I was nervous about my colon cancer screening and he was reassuring and patiently answered all of my questions. His staff is friendly and very helpful.
I am so impressed with my visit with Dr Nassos today. More so than I have been with a doctor in a long time. Even as a first time patient with an appointment made the day before, not only was I seen right away, but the doctor took more time with me than every other doctor I've seen in years put together. After a decade of daily shoulder pain, I feel hopeful for the first time in a long time! Will definitely recommend him to anyone needing orthopedic care!
Dr. Nassos was thorough in his explanations and really listened to how I wanted to be treated. He offered alternatives and explained each option; offering suggestions based on what he understood of my personality and life habits. Considering I was a first time patient, that was pretty impressive. He and his staff are all lovely and I would highly recommend his medical services.
I really like Dr. Nassos. He was very warm and caring. I had a painful wrist that I was worried about. He was reassuring and recommended a very simple treatment to resolve the issue. I will recommend Dr. Nassos to friends and family.
The wait was a little long and the xray tech was late in getting to the office, for which the doctor apologized. Excellent bedside manner and he took the time to explain the next steps and what he thought might be going on with my shoulder.
He was wonderful. Very generous with his time. Everyone in his office was professional and friendly. There was a mix up and he unfortunately did not take my insurance. I was able to get his opinion and a prescription for physical therapy.
Dr Nassos was great, but Synapse is a very large medical group and they're not super efficient - I've been twice now and had long waits both times. All of the front office people were very nice and it seemed like they were working to keep everything moving quickly; I think they're just understaffed.
Wonderful doctor! He took his time with me, explained in plain terms what my condition was/is, and, instead of taking the opportunity to do X-Rays (which I was prepared to shell out for), he treated me right on the spot and I've seen a major improvement. It's my belief that Many doctors would've done X-Rays anyway, even if they know the situation doesn't warrant it or it's completely unnecessary. The fact that he spared me from this absolutely floored me. He also suggested that surgery was not likely necessary and, being an un-insured patient, this was incredible news. I may still have to have surgery, but it won't be because a doctor wanted to rush in and out of the room and just "get it over with," thus leaving me with the easiest and typically-acceptable solution. Dr Nassos sincerely took time with me, has a great personality, and really knows his stuff. I wouldn't hesitate to go back to him for further needs.
Totally great- and appreciated that he didn't try to get me to spend money on procedures that weren't 100% definitively necessary.
Very positive, good energy.
I feel he was very professional and more than willing to answer questions. This was my first visit, but likely not my last.
I have had a chronic problem on my left shoulder for years. Recently I reinjured and was having quite of bit of pain. Dr Nassos was very attentive to my history and soon found the problem... A cortisone injection on the right spot has given me not only relief from the pain I was having but also more mobility. Just two days later I am able to move my left arm and shoulder with much more ease than the whole past year.
What a great doctor with great attitude and respect,
Dr. Nassos was the best choice I could have made for my hand problem. I came in for a follow-up for a fracture and he was so thorough. He explained everything in down-to-earth terms that made me feel at ease.
Excellent Dr. who made me feel comfortable and actually listened to my problems and gave his thoughtful feedback. The fact that I am even taking time to review him speaks volumes for how great he is.
Very clear, efficient and helpful.
I am pretty sutisfied.
very nice office and staff!
I would highly recommend Dr. Nassos.
